LTC2935IDC-2

Supervisors Overview

The LTC2935IDC-2#TRMPBF is a voltage supervisory circuit manufactured by Analog Devices Inc. It monitors up to eight independent input voltages and provides a push-pull output for power-fail detection. The device features selectable threshold voltages including 2.25 V, 2.4 V, 2.55 V, 2.7 V, 2.85 V, 3 V, 3.15 V, and 3.3 V. It operates within a supply voltage range of up to 5.5 V and maintains an accuracy of 1.5%. The reset delay time is specified at 200 ms, with a maximum operating temperature of +85 C and a minimum of -40 C.

Supervisors Feature Summary

• Monitors multiple independent voltage inputs simultaneously
• Provides selectable threshold voltage options for precise supervision
• Features manual reset capability without watchdog timer integration

Supervisors Applications

• Power-fail detection in industrial control systems

Supervisors Procurement Notes

Verify the specific suffix and package variant against the official datasheet before ordering. Confirm availability status as distribution channels may indicate limited stock or discontinuation. Ensure the selected part matches the required operating temperature range and threshold configuration for the target application.

Supervisors Selection Notes

Select this component when simultaneous monitoring of multiple voltage rails is required. The push-pull output simplifies interface design compared to open-drain alternatives. Verify that the available threshold combinations align with the specific voltage levels present in the system architecture.

Supervisors Part Context

This part belongs to the LTC2935 series of ultra-low power supervisors. It is designed for applications requiring reliable voltage monitoring with minimal quiescent current consumption. The series offers various package options and threshold configurations to suit different board space and performance requirements.

Supervisors Replacement Considerations

Direct substitutes include other variants within the LTC2935 family such as LTC2935ITS8-2#TRMPBF or LTC2935CTS8-2#TRMPBF, provided the package type and threshold settings are compatible.
